Fat vs. rocker?

[casey_cope]

So I was thinking about this the other day and I was wondering what would work better in powder. A super fat (140-150mm) full cambered ski or a fully rocketed, reverse camber thin ski? The fat ski would disperse your weight a little more so it wouldn't sink on flat but the reverse camber ski, your tips wouldn't go beneath the snow. Your thoughts

Depends on how heavy the snow is

Buoyancy is key. Most surfboards, water skis, wake boards etc have a varying degree of rocker. Personally I think flat camber and early rise tips and tails would work best.
